why are imperfect fungi considered "imperfect"? what would have to happen to change the classification of an imperfect fungus to a perfect fungus?

Imperfect fungi reproduce asexually as they reproduce by simply cloning themselves. That means they don't have genetic recombination during their life cycles. So they are likely to store genetic weaknesses in their genome.

Imperfect fungus species can be shifted into perfect fungi taxon if the sexual reproduction of this species will be discovered.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
